Using Facebook Login For Leaving Comments On Blog?

I had seen this on some websites and then i read about it on SEOMoz blog .

What do you think of using Facebook login for leavin comments? I was kind of reluctant to leave comments in places that i had to use my facebook login (mainly for privacy reasons - even though my facebook is 100% private)

As a site owner, I like the idea that if someone leaves a comment on my facebook comments section then it gets posted in their friend's news feeds. And if their friends comment, it gets added to my page. It has brought some extra attention to my site.

My main issue is that I can't find a place where you can moderate comments. If you go to facebook.com/insights there is data on how many comments have been left, but I can't see a place where I can moderate the comments. If you have thousands of pages on your site, it's going to be difficult to moderate comments.

The other issue, like you said, is that some people may be reluctant to comment if it's going to go on their facebook page.

Some have had issues with the fact that these comments are iframed. But there are solutions available to make the comments crawlable.

I do like the idea, but if I could figure out how to moderate the comments I would be happier!
